The power of DIBELS® is expanded with a new assessment tool developed for young Spanish-speaking readers. The Indicadores Dinámicos del Éxito en la Lectura (IDEL™) are measures to evaluate students’ performance in beginning reading skills in Spanish. IDEL measures are not a simple translation of DIBELS ... They are a reinvention of DIBELS measures. IDEL measures reflect that Spanish, like English, is an alphabetic language, but that Spanish, unlike English, has a regular orthography in which letter sound correspondence is more transparent.
